The Dharma Tee is a made to measure and size inclusive pattern. You will need any light worsted weight or DK cotton yarn (8ply) in any colours of your choice. I used around 350g/700m for a size small (UK 8).
You will also need a 4mm crochet hook.

This pattern is an intermediate level but I think its also suited to advanced beginners, the pattern has photos throughout each step and very detailed instructions.

The design is made from the top down and is worked in continuous rounds, this means you do not turn your work. You will start from the hole your head goes through, and increasing until you meet your measurements.
The design uses a very textured and detailed stitch and is a easy 4-row repeat.
